Rhododendron plant named ‘BAILEC’

ABSTRACT

A new and distinct  Rhododendron  cultivar named ‘BAILEC’ is disclosed, characterized by double red flowers, with uniquely rosebud shaped flower buds. Plants bloom Spring, Summer and Fall and have an attractive mounded shape, and are easy to maintain in the landscape. The new cultivar is a  Rhododendron , suitable for ornamental garden purposes.

Latin name of the genus and species: Rhododendron hybrid.

Variety denomination: ‘BAILEC’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program by the inventor, Robert Edward Lee. The inventor's intention was to develop Rhododendron hybrid plants with re-blooming characteristics. This new variety, hereinafter referred to as ‘BAILEC’, was discovered as a seedling, resulting from the open pollination of Rhododendron ‘Roblea’, U.S. Plant Pat. No. 12,142. The pollen parent is unknown. The open pollination resulting in the new variety occurred during 1994. The new variety was selected by the inventor during 1997 at a commercial nursery in Independence, La.

After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘BAILEC’ by vegetative terminal cuttings Fall of 1997 at the same commercial nursery in Independence, La. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. At least three generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘BAILEC’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BAILEC’ These characteristics in combination distinguish ‘BAILEC’ as a new and distinct Rhododendron cultivar:

-   -   1. Unique Spring, Summer, and Fall blooming.     -   2. Unique flower bud shape, similar to a rosebud.     -   3. Mounding plant habit.     -   4. Double red flower.     -   5. Good landscape growth habit, easy to maintain at a size of 3         feet by 3 feet.     -   6. Hardy to Zone 7.

COMPARISON TO PARENT VARIETY

‘BAILEC’ is similar in most horticultural characteristics to the seed parent Rhododendron hybrid ‘Roblea’. Plants of the new cultivar ‘BAILEC’ however differ in the following:

-   -   1. The new variety has a red flower, the seed parent has a         salmon colored flower.     -   2. The new variety produces a uniquely shaped bud, resembling a         rosebud, not observed in the parent variety.

Pollen parent is unknown.

COMMERCIAL COMPARISON

‘BAILEC’ can be compared to the commercial variety Rhododendron hybrid ‘Roblec’ U.S. Plant Pat. No. 15,339. Plants of the new cultivar ‘BAILEC’ are similar to plants of ‘Roblec’ in most horticultural characteristics, however, plants of the new cultivar ‘BAILEC’ differ in the following:

-   -   1. ‘BAILEC’ flowers are red, flowers of ‘Roblec’ are pink.     -   2. Plants of ‘BAILEC’ grow more slowly than plants of ‘Roblec’     -   3. Mature foliage of ‘BAILEC’ is dark green, near RHS Green         139A, mature foliage of ‘Roblec’ is Yellow-Green 147A.

‘BAILEC’ can be compared to the commercial variety Rhododendron hybrid ‘Conlea’ U.S. Plant Pat. No. 10,438. Plants of the new cultivar ‘BAILEC’ are similar to plants of ‘Conlea’ in most horticultural characteristics, however, plants of the new cultivar ‘BAILEC’ differ in the following;

-   -   1. ‘Bailec’ has red flowers, ‘Conlea’ has red-purple flowers     -   2. Plants of ‘Bailec’ are more slow growing.     -   3. Mature foliage of ‘BAILEC’ is dark green, near RHS Green         139A, mature foliage of ‘Conlea’ is Yellow-Green 147A.     -   4. Foliage of ‘BAILEC’ is more pubescent than foliage of         ‘Conlea’.
